The diamond drill. (Crystal Falls, Iron County, Mich.) 1887-1996, 1887-05-21


The Dunn mine is property Of large
proportions and is valuable acquisi-
ton TO the list OF shippers from this dis
trict. The machinery ~ rapidly being
placed in position, under the supervision
81 c. NJ. Wheeler, OF Marquette, who is
an owner in the property. The ground
around the mine is being cleared up and
everything is being done 10 put the mine
in good shape To begin active mining at
such time AZ the spur track iscompleted.
The vein has been traced by test pits
distance OF 4S3 feet, which does not de
fine it's length AZ pits at each end are in
ore. The course OF the vein tx about
north and south, with the hanging wall
on the west which is jasper and quartz
Stripping has been done along the hang
ing wall distance OF over two hundred
feet, and about thirty feet wide, bareing
the vein which at the west lies under only
foot or two OF Gaping, which becomes
deeper IA work il carried to the east.
No foot wall has yet been found and the
depth OF the deposit is yet unknown. A
pit at the extreme north end is down
thirty feet with twenty foot drift run
ming west, all in ore; the vein ut this
point has been tested across n distance
Of thirty-seven feet. Another pit mt a
little north Of the center has been car
ried down on top OF the vein, which
slants to the east at an angle OF about
forty degrees, distance Of about forty
feet where n cross cut was driven TO the
hanging wall on the west At the center
another pit was lowered forty feet, from
which drift was driven nineteen ieeteast
and one twelve feet west To the hanging
wall. South Of this pit has been low
cred thirty-six feet, all i'm ore and at the
extreme south Of the exploratory work
a pit il down thirty feet in ore. All OF
the pits described are not over twenty
five feet east OF the hant,s,g wall, but
others are down along the formation at
an average distance Of fifty feet east OF
the hanging wall The vein has been
shown by prosecuting to be sixty feet
wide near the center, but M no foot wall
has been found there are, as yet, no
accurate means 81 determining the ex-
act width OF the deposit. A force OF
twenty-five men are engaged on theprop-
erty, whose chief work at present is strip
ping. The west side Of the mine, by rea-
son OF the small quantity OF Gaping will
he worked ~ an open pit, but stopping
will be carried ON mt the east side OF the
mine, where the Gaping Is Of "A consid-
cradle thickness. The foundation for the
stock pile is now being built and pockets
will be erected at once. George Dunn Is
the mining captain and informed the
writer during recently visit, that he il
81 the opinion that the first years work
can be carried ON as cheaply as that
done at any mine ON the Range. and
bases his assertions ON the fact that the
general lay OF the mine IL greatly to it's nd.
vantage. The ore is a hard, compact
non Bessemer, running high in metallic
iron. IL IL said that the spur track will
he completed early in July.
People who invest in mining operations
without any knowledge OF this branch o
industry, as rule expect too much II
requires both patience and money, and
plenty OF each in ordinary cases, TO find
ore, and then, after the ore is found, th,
development Of the find" into a mine
sometimes requires years and "A great
ontlay OF money Co provide IL with ade
auate machinery. Exceptions OF cours,
occur i'm all mining countries, and mines
have been found which pay from the sur
face But the history Of all OF the Older
mining regions show these eases TO b,
rare. The thing of finding paying min,
il considerable of lottery business
There are eases where thousands Of tons
of first class merchantable ore has beer
taken from the surface and and then th,
deposit has pinched out, and ten time,
the value of the out put has been fruit
lessly expended in efforts 90 find more
No one should invest money in minin,
operations unless willing TO take The
chnnces. Men without means, who pos
s,,.s some little knowledge 81 mining, car
more safely risk their time, II they hav,
nartics associated with them who fur
nish the means Of subsistence, and the,
sometimes reap rich reward for then
labors. But man h foolish Go risk hil
